CALEB G. PUOKETT, OF CERRO GORDO, INDIANA.

IMPROVEMENT IN DRAIN-VALVES FOR PUMPS.

Specification forming part of Letters Patent N o. 36,365, datedSeptember 2, 1862.

To all whom, lt may concern.-

Beit known that I, CALEB G. PUOKETT, of Cerro Gordo, in the county ofRandolph and State of Indiana, have inventedva new and Improved Devicefor Letting Off Water from- Pumps, and I do hereby declare that thefollowing is a full, clear, and exact description of the same, referencebeing had to the accompanying drawings, forming a part of thisspecification, in which- Figure 1 represents a vertical central sectionof my invention. Fig. 2 is a front elevation of the same.

Similarletters of reference in both views indicate corresponding parts.

The object of this invention is to provide simple and effective meansfor letting 0E water from pumps to prevent freezing.

The invention consists in the arrangement of a screw-rod provided at itslower endfwith a valve or stopper of cork or other suitable material,and passing down through asuitable case on-the side of the pump-stock,in combi nation with a pipe emanating from the lower part of thepump-stock and communicating with the interior of the same in such amanner that by means of said screw-rod the pipe can be opened and closedat pleasure, and that when the pipe is open the water remainingin thepump is permitted to ooze out, and the freezing of the same in 'the pumpis prevented.

To enable those skilledin the art to make and use my invention, I willproceed to describe it with reference to the drawings.

A represents the pumpstock, from which the pipe B extends down into thewell. A bucket or plunger, C, which is operated by a handle, D, and avalve, E, constitute 'the ordinary working parts of the pump.

From the lower part of the stock A a pipe, a, extends, the outer end ofwhich is bent upward, so as to meet the valve b, which is secured to thelower end of the screw-rod c. The valve b consists of a piece of metalcovered on its under surface with cork or other suitable material; or itmay be made of a hollow metal case filled with cork, leather,india-rubber, or any other suitable material. The screw d, which carriesthe rod c,screws 'into a bracket, e, which projects from the side of thestock A, or which forms the top of a metal case, f, that is rmlyattached to the pumpstock,and which covers up and protects the valve band pipe a. When applied to a pump, the pipe a will be placed down aslow as possible close over the bucket when the same has arrived at itslowest position, so `that all the water remaining in the pump can be letout, and the screw-rod c will be made sufficiently long to extend upabove theground, so that the valve can be conveniently operated. Thecase f protects the screwrod, the Valve, and the pipe against injuryfrom the dirt and stones. By these means 'the water from the pump can belet off quick or slow, as may be desired, and the whole device is sosimple that a child can manage it. The valve and pipe are perfectlyprotected by the case f, so that the dirt may be put against thepump-stock without preventing said parts from working,and the screw-rodc can be taken out and the cork or other material repaired or replacedby a fresh piece without taking away the dirt or platform over the well,Vor without disturbing any part of the pump. The several parts of mydevice are made of metal which will not rust nor impart to the water anydeleterious properties, and said device can be attached with littletrouble to any pump,old or new. It may be applied to any side of thepump-stock; but it will be the most convenient to have it right underthe handle, so that it can be lreached when done pumping withoutgoinground the pump.

I am aware that side pipes connecting the valve-chamber with theeduction pipe and provided with a valve, so that the water can be drawnfrom the valve chamber and conducted to the well,are old. I do not claimthe above as my invention; but,

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

The combination of the box f,screw valve rod c, valve b, and pipe a,with the pump-stock A, in the manner herein shown and described.
